We investigated the customer experience of more than 20,000 outdoor adhesive hooks, and found that more than 70% of the complaint was that the light hooks were not competent for his work, which made the string light fall off. It is really a headache problem. After more than 200 tests and continuous improvement of the design and materials of the hook, we choose the best weatherproof adhesive sticker to cope with various unpredictable and harsh outdoor environments. We finally designed this large double-clips outdoor string light clip. We believe it can bring a good shopping experience and we promise a full refund. If you encounter any problems during use, you don't need to provide a refund, you only need to contact us by Amazon.
